2010 Touareg TDI Stop/Start switch inop.

[atikovi]

Long time no see. Picked up this Touareg recently. The remote has a new battery and the remote functions work fine as well as the keyless access. The Start/Stop button doesn't do anything when I press it. Not even a message on the dash. The illumination does work so it must be getting some power. The button cover is broken, but I don't want to waste $25 replacing that if the switch itself is bad.



Scan shows,

00184 - Control Circuit for Engine Start/Stop Switch
007 - Short to Ground

To isolate the problem being in the switch or the wiring, can I disconnect it, erase the code and see if it returns? If it does, the switch is OK and there is a wiring problem on the circuit? How can I see Live Data that would show when I'm pressing the button?

I've also read somewhere that the Start/Stop switch can be coded out. Will I be able to tell from the scan if that is the case, and if so, how to activate it again?

So first off, you are correct about the "short to ground" issue. That usually means the control module isn't seeing power flow OUT to the relevant component, in this case, the switch itself. If it really is only $25 to replace (with a GENUINE switch, right??!!!), then I'd say load the parts cannon and fire away. Yours is damaged anyway, so it won't hurt to replace it.

I also see this error which probably isn't related, but might cause you other issues down the line. It indicates a wiring issue somewhere in-line with your instrument cluster:

And finally, you've got errors for all (4) TPMS sensors as well as a few battery voltage errors. I'd look into the health of both if I were you, though these are definitely unrelated to your Start/Stop switch issue.

Note to @atikovi: we don't generally like clicking links to view scans. ]

Maybe my memory is off, but I recall being told not to post the whole scan line by line as it takes up so much space. Next time I'll have it directly in the thread.

$25 is just to replace the broken button cover. A genuine new switch is around $150

Have a set of cheap TPMS sensors from Ebay on order. I'd think the clogged DPF would be a bigger concern, no?

In that case, time to get a wiring diagram <--- clickable link and start verifying the wiring to/from that switch.

You're likely going to regret trying to cheap out on electronic parts for a German vehicle. Did you notice that "eBay" turned into a clickable link? I can't tell you how many times we've seen C.R.A.P. <--- hover your mouse over that for a definition cause issues for people around here. When it comes to electrical/electronic parts, best to stick with dealer or OE parts from reputable vendors.

As for the DPF, is it actually clogged? Thanks to DieselGate, VW made their software very "sensitive" to anything that MIGHT be an issue. It would be a good idea to remove it and check, but I'm not concerned just because one single code is present.

You should always post the whole scan, best way is to use the forum editor </> icon which will open a popup to paste the scan into and also create the code tags that wrap the scan into a manageable size on the forum.

 

[SaVAGeSoot]

As for the DPF, is it actually clogged?

It's not really.... but it is full beyond the level at which it will allow him to just do a simple regen due to the fact that the vehicle has been driven with critical failed components and repairs were ignored... as such, the autonomous active regens were not taking place for a long time..... I know this, because of other information he's supplied on other forums.

$30 vs. spending more than 10% of what I just paid for truck to get OE sensors? No thanks. Will put a piece of black electrical tape over the warning light first. And I just typed "Ebay", not sure why there is a link to some weird Ebay song. I didn't add that.

The only thing I'm concerned about is the CEL is on so it wouldn't pass an emissions inspection.

You sure do have a fan bud... I love watching you load up the cannon with your diagnostic approaches.

That link was auto-added by the forum because eBay is the most common source of frustration around here. As much as I hate the attitude that goes with it, there is quite a bit of truth in the phrase "German vehicles are pay-to-play". C.R.A.P. parts from eBay, AliExpress, etc. almost always cause more problems than they purport to solve. Fortunately, we don't have MOT in the USA, so if the eBay sensors HAPPEN to work, or if you're happy with the tape-over-the-light solution, then by all means, be happy.

 

[atikovi]

I disconnected the switch and removed it to take apart. Found nothing obvious, just went over the internal contacts with a cleaning brush and reassembled. Plugged it in and it now works like it should. Maybe some terminal fretting on the pins of the connector? Anyway, off to order a switch button cap on E b a y.

But of course something else came up in the engine after re-scanning. Codes for the glow plug controller.

I did replace glow plugs 1 and 3 yesterday because my Autel scanner found codes for them that never showed on Vagcom,



They did test bad after removing them. This morning at about 50° it took 10-15 seconds of cranking to start. I'll create a new thread if I can't figure it out first.
