    2017 Tiguan 2.0 TDI G28 / G40 Correlation Mystery

    Thanks for the replies and advice. The timing belt was replaced about 8,000 miles ago but, in exasperation, we have checked it again and found all as it should be. In any case, as stated, the engine starts and runs fine until the temperature reaches 75 degrees, consistently. My contention is...

    2017 Tiguan 2.0 TDI G28 / G40 Correlation Mystery

    So this 2017 Tiguan 2.0 TDI seems to start and run fine every day. But, at around 75 degrees on the temperature clock the MIL appears and the attached VCDS scan indicates P0016, a malfunction with the G28 Crank Speed Sensor correlation to the G40 Cam Speed Sensor. Naturally this DTC cannot be...

    Can't find P1720

    Thanks Uwe. Yes, he says he's seeing 'implausible signal' so I'm guessing it's a sensor problem or a wiring issue. I'll see how I get on with it at the weekend.

    Can't find P1720

    I've been asked to take a look at a friend's VW Tiguan which has developed a transmission problem. He has already scanned it with a lesser quality 😉 scanner and tells me it's showing the DTC P1720. I intend to have a look at it at the weekend but checking out our forum I can't find anything on...

    2000 Caddy Pickup Not Communicating

    My MF 35X also but strangely any Fordson Major from 52 to 64 only ever needed a nod from the driver, hot or cold. What price progress, eh?

    2000 Caddy Pickup Not Communicating

    Of course! Finally I get it. The reason I can't access certain individual modules is simply because they're not there!! What threw me was when I selected the first half dozen or so none of them would scan so I assumed the worst. Turns out the only accessible modules are the 25 & 41. 25 is fault...

    2000 Caddy Pickup Not Communicating

    That url doesn't seem to work for me.😒 but I have the screen ok. So therefore I can't access the modules individually on this vehicle? The only way to communicate with it is to choose the model via the dropdown list which is via Auto Scan. SELECT - MODULE is not an option. Think I have it now?

    2000 Caddy Pickup Not Communicating

    Yes, I believe it has ABS and airbags but there are no MIL's. That's where I can't access the dropdown list. The list is only available when I select "Auto Scan"?

    2000 Caddy Pickup Not Communicating

    Cheers Dave, That sorted it ok. I hadn't previously needed to use the dropdown list. I see it worked for me for Auto Scan and returned the result below Am I right in thinking it was only able to detect addresses 1,3,15,25 & 41, showing results for just 25 & 41? And is there a way to access the...

    2000 Caddy Pickup Not Communicating

    Hi Derek, Thanks for the quick response. The LED flashes red on first connection, then yellow and then green when I connect the laptop. The first photo here is just with the ignition off, I didn't think to switch it on, sorry. The radio is aftermarket so I removed it & started the vehicle which...

    2000 Caddy Pickup Not Communicating

    So I'm trying to scan my 2000 Caddy Pickup to check on a glow plug issue. The interface connector will flash when connected to the OBD plug but then no communication with any modules. I'm wondering is the vehicle too old or is the OBD system incompatible with my VCDS? The VIN is WV1ZZZ9UZYT003150.

    As suspected, with both modules isolated there is still continuity at pins 2,3,5 & 6 of T6ap. Initially, given that the loom is extremely difficult to access at it's lower run along the steering rack / suspension cradle, we had planned to make up a new 6 wire loom and simply bypass the old one...

    Overnight, it strikes me as too much of a coincidence that the two outstanding faults, J500 & G266, share the same 6 wire loom. Further scrutiny of the loom today reveals continuity between pins 2, 3, 5 & 6. The plan for tomorrow is to disconnect both modules at their connectors T3a (J500) &...

    Soooo, finally some progress. After checking all fuses on holders A,B,C & D (SC13 now behaving good with sensor G266 disconnected), we turned to locating and checking as many relays as we could find. We then attempted to access the non-reachable modules firstly pin-pointing their location (some...

    Not a lot to report yet. We had already ruled out the G266 by disconnecting it but weren't aware of the Start / Stop connection. Will try isolating that next. Also, we're currently trying to source replacement modules for 9 (Cent. Elect.) & 19 (CAN Gateway) purely to see if we can establish...

    Currently fuse 13 in the passenger compartment fuse box is blowing and indicates a short circuit so I need to begin the process of elimination. My biggest problem is locating the various modules as there appears to be very limited information on this model.
