Bank 2 all cylinder misfires, cam sensor faults

[alvocado]

I completed the cam girdle gasket replacement on my '08 A6 and replaced the upper timing chain tensioners as preventative maintenance since they were removed for the procedure. All four cams were removed from the car as part of the gasket replacement but were removed and installed using cam locks to ensure correct timing and positioning at TDC. The engine was turned over two full rotations manually after reinstallation and all cams returned to correct position before closing everything up.

Upon startup, I'm getting cam position sensor faults and cylinder misfires on bank 1. I replaced both cam position sensors and verified the ground wire on the back of the engine was secured to the block. The vehicle ran fine before the repair which was done to address oil leaking into the spark plug wells. Any direction on troubleshooting would be greatly appreciated.

Here's the VAG scan including the fault details.

Upon startup, I'm getting cam position sensor faults and cylinder misfires on bank 1. I replaced both cam position sensors

Sounds like you were very thorough, however often times aftermarket sensors can create problems or send you in a wrong direction: are those sensors genuine oem ? Did you replace the cam position sensors before , as part of the service, or after the trouble codes?

You may have to verify timing once again. Be sure you are at TDC (manually check with a long wooden dowel rod down the cylinder etc.) ; you may be misreading the marks on the crank pully (?).

I believe you can check the cam / crank synchronization in advanced measuring blocks.
Start VCDS used at 6:00 , 6:57 (note values , here they are zero, however yours will most likely show some values). I believe you want to be below 4 degrees to be within spec. ; but please verify.

 

[alvocado]

Cam sensors were replaced after getting the faults using OEM sensors from the dealer. To get to TDC, I rotated the crank until all four cams were oriented with the threaded bolt holes facing upwards, allowing installation of the cam lock bars which thread into the holes. The crank lock pin was then inserted on the bottom side of the engine to verify correct crank position. I'm not aware of any markings on the crank pulley which likely would be difficult to see if they are present.

I'll try to get a cam/crank sync measurement as outlined above provided the car will stay running long enough to take the measurement. Will report back afterwards.

 

[alvocado]

I'm not seeing how to measure cam/crank sync in advanced measuring blocks. I selected timing retardation for all 6 cylinders but the data returned 0.0KW and didn't seem to be properly reading the block. I also tried pulling camshaft adjustment adaptation values in block 093 but again, no data was registered while the car was running. A fresh scan of codes still shows the same faults for both camshaft position sensors and all 3 left bank cylinders misfiring and intermittent disabling.

 

[stefdds]

I believe it is 01 Engine ---> select Advanced Measuring Values (left side , in Basic functions)-----> search field at top right and type in "timing" then check the box for all the cams -----> select or run . note time 6:46 on video.

 

[alvocado]

That's the location I was using but I don't have any options for cam in the selection list.

 

[stefdds]

I see! (thank you for the pictures) did you try some different search terms ? Sync or cam or Bank ....... Or, start with A's, B's, C's....... and see what populates.

 

[alvocado]

Progress. This is surprising as I would expect to see 4 cams total (2 intake, 2 exhaust).

 

[stefdds]

yes, I see what you mean: (?) 089-2 for example (exhaust). Bank 2 is your non-fault side , once you get some data for B2 , then you can compare to B1. Check your connections / wiring on those sensors (just to be sure). Glad your making progress as VCDS will save you alot of time vs. manually checking.

 

[alvocado]

What would prevent group 093 readings on both bank 1 and bank 2?

 

[stefdds]

What would prevent group 093 readings on both bank 1 and bank 2?

It may not be a valid group number (in your specific case).

I would try a couple of different Group numbers: 090 , 089, 094 just to see what populates those fields.

2008 Audi A6, 3.2L Quattro. Following removal of the cams to replace the intermediate spark plug tube gaskets between cam girdle and head, I'm getting misfires on bank 2 cylinders 4, 5, 6 and both bank 2 cam sensors faulting. Here's a rundown of the repairs and troubleshooting so far:

• Removed cam girdles including all four cams for gasket replacement. Followed factory procedure exactly; used Baum engine timing tool kit to lock all cams at TDC and inserted crank lock pin.
• Removed and reinstalled girdles with new gaskets and flange sealant. Cam locks and crank pin remained in place.
• Installed new OE upper chain tensioners.
• Installed cam adjusters, applied light tension using camshaft sprocket holder to cam adjusters and tightened to spec.
• Released new chain tensioner pistons
• Removed cam locks and crank pin, manually rotated crank 2 full revolutions. Cams remained in sync with threaded holes aligned and facing upwards, everything moved as expected
• Ground wire attached to back of engine required a new ring terminal. Installed new terminal.
• Completed reassembly and started engine
• Car ran very rough and immediately threw CEL with codes below
• Replaced both bank 2 cam position sensors with new factory units - no change
• Measured resistance of both bank 2 VVT solenoids: 7.4 ohms and 7.5 ohms, consistent with bank 1 readings

I tried to take an engine data block 093 reading to assess chain tension and possibly identify an issue with chain and sprocket engagement and/or the new tensioner but the fields remained blank while scanning.

Any help on additional troubleshooting before opening back up would be appreciated.

Check the cat on the left bank to make sure the primary monolith has not collapsed

 

[alvocado]

Is there any correlation to the repair that would have suddenly caused a cat failure? The car ran fine before the repair which was done solely to address oil leaking into the spark plug tubes? Not ruling it out but trying to go through a checklist related to what was touched/replaced before extending beyond the engine.

 

[EuroX]

I would say your issue is timing, or bent valve at this point. Why were the cam adjuster removed?? Were they changed??Did you mark the running direction of each chain prior to removing??

The mistake your made is the following. You tightened cam adjusters to spec prior to pulling the chain tensioner. You need to pull chain tensioner first. The cam adjusters should be on but be able to freewheel somewhat. Repair manual clearly states this:

–	Replace camshaft bolts.

–	Place camshaft timing chain onto drive sprocket and onto camshaft adjusters and loosely thread in the bolts -1- and -2-.

●	Both camshaft adjusters must be able to still be rotated on camshaft and must not tip.

–	Remove Locking Pin -T40071-.

– Set the Counter-Holder -T10172- with Pin -T10172/2- in place on the camshaft adjuster of the left intake camshaft. – Hold the camshaft timing chain pretensioned by pressing on counter-holder in direction of -arrow-. – Simultaneously, pre-torque the camshaft bolt using the Multipoint Socket -T10035- and torque wrench. ● Tightening Specifications: 40 Nm. – Continue holding the pretension on the intake camshaft and pre-torque the bolt -1- on the exhaust camshaft. ● Tightening Specifications: 40 Nm.

– Tighten camshaft bolts -1- and -2- on left cylinder head to final tightening specification. ● Tightening Specifications 80 Nm plus an additional 90° turn.

 

[alvocado]

My apologies, I noted two steps in reverse above. I pulled the tensioner pins T40071 before pre-tightening and final tightening of the cam adjusters. The adjuster bolts were finger tight when the pins were pulled. With the chains tensioned, I did not feel much movement when applying the pretension on either side. I did mark the chains but since they remain attached to the lower sprocket, it wasn't clear why that's necessary.

The cam adjusters were removed in order to pull the cam girdles with cams locked in place, which is necessary to access the spark plug tube seals. With 151k miles, it made sense to change the tensioners preventively as well. The original adjusters were reused.

Yes, moving from the new member forum to the appropriate forum based on topic following account verification. Appreciate your replies.

Honestly to me it sounds like its out of time. However have you tried clearing the faults?? See if they return??Also does the vehicle start and rung or is it just cranking no start at this point?? Although crasher makes a good point I find it hard to believe that if you didn't have issue before this repair that all of a sudden a catalyst would fail. To me it sounds like its directly related to the repair that was performed. were the cam tools installed on both banks or just one bank??Are we sure none of the wiring at the rear of the engine is not disconnected?? There is 2 or 3 crucial connectors at the rear of that engine I would make sure they are completely seated. Or you can try to check for spark on bank1 or check wiring for both cam sensors. However I find it odd that all these issues occured after the repair which to me based of my experience tells me its related directly to the repair at this point in time. Checking wiring and for spark we can try to rule out basics before condeming timing. These engines are simple all you need is, fuel,ignition source, and compression.

The engine cranks much longer than normal before catching and runs very poorly on startup. I've only scanned for codes once to avoid running it more than necessary. After turning off the engine and attempting a restart, the engine will die after a couple of seconds unless I give it some throttle.

Both sides and all four cams were locked with the cam tools as well as the crank pin in place prior to removing the girdles or timing chain components. It's puzzling how it could end up out of time based on everything being locked with both sides in sync but the symptoms lead that direction.

Is the best option to check timing removal of the valve covers and verifying the cams will align at TDC with the cam locks in place? I assume that manually rotating the engine will test if there's a bent valve based on resistance. I'll pull the plugs to eliminate compression when rotating.
