E85 Lots of errors

[iamnotme]

Should I be able to talk to the Tire Pressure Monitoring module, because that doesn't want to play at all, no matter if my lead is in K or D Can mode

I may be wrong, but I think that is the module associated with the TPMS transmitters on the tyre valves, as used in later models. Your car should use the ABS sensors to measure and compare wheel rotation speeds to detect a tyre deflating. As such, the functionality is contained within the DSC unit. A caveat here is my very basic understanding of this system and based on my interpretation of the wiring diagrams.

Yeah I had come to this conclusion after reading a few different things online, and if I used my brain it would be obvious as I had new wheels fitted and there weren't any pressure transmitters involved.

I even tried removing the connectors from the DME and checking the pins, everything looks ok there. Once I reconnected and checked it, all the faults came straight back when I tried to clear them.

 

[iamnotme]

Ok, it gets weirder. I've put the manifold back on, everything else back together, but now the car doesn't start

The crank sensor error appears to have disappeared along with the throttle pedal error. I've checked a few other module and the CAN errors appear to have cleared on a few of them, but I'm not sure if that's because the engine hasn't actually started.

You’re not wrong there this is so annoying

The faults came from nowhere a couple of weeks ago, and now it’s changed behaviour.

It’s supposed to be getting a full custom exhaust fitted next week, but I’m probably going to have to cancel it

 

[bigwinn]

I think you need a closer look at all the looms, earth points and wiring. If you’ve had some rodent damage you need to eradicate any further issues

 

[iamnotme]

All the other bits of conduit are intact. The only possible one would be the MAF as that isn’t in plastic conduit. It is also away from the side of the engine where the rat decided was a nice warm home.

I’ll check the MAF cabling tomorrow

 

[iamnotme]

Back on the car today as I was busy yesterday.

I've had the battery on charge, so that is fully charging. When I checked on INPA the voltage dropped to 9.4 on cranking, then jumped up to 10.4, which seems a bit low to me. I have a spare battery and now it only drops to 10.7 then slowly decreasing.

I also checked some other values in INPA and one that stuck out was ansaugslufttemperatur which using translate seems like intake air temperature. It was ready 66 degrees C which it most definitely isn't. Is this figure derived from the MAF sensor, or is there another sensor that measures air temperature? When I unplugged the MAF it dropped to 17, before rising to 27 with the MAF connected.

 

[enuff_zed]

Yes the MAF measures flow and intake temperature to calculate air mass.

 

[iamnotme]

Yes the MAF measures flow and intake temperature to calculate air mass.

Thought so, but could this just be another red herring in the world of my cars weird electrics? Surely if the cable was damaged it wouldn't read 17 degrees with the MAF disconnected, or does it factor in cable resistance?

The other week it was showing -40 which I presume is the reading if it doesn't have a circuit. My MAF is actually at the very front of the car, behind the grill, because of the supercharger. I'm guessing they would have had to extend the cabling to do that, as the MAF would normally be in the engine bay. I'm not getting a MAF fault now though which I was when I started looking on Thursday. I'm going to check the cabling anyway, but it still feels like I have more questions than answers.

 

[iamnotme]

Well the MAF has a problem wired by jokers, I'm surprised it has lasted this long wrapped in cloth tape where it is going to get very wet

I hope there isn't joint further back, though my money is on it being so

 

[iamnotme]

Success with the MAF, it now reads a steady 12 degrees, which isn’t bad. My weather station shows 9.

Still have 8 sensor faults on the DME though. Start looking at those next for anything common such as voltage.

 

[iamnotme]

Found the other joint

They're all repaired now, and fuse F01 remains intact. I found out what my spare green connector was for, it's the crank sensor. I didn't realise that was under the starter, so that's back in place.

All that's stopping from starting now, is some ham fisted oaf(me) catching the injector loom when putting the manifold back on. Hopefully then the DSC fault moaning about not seeing the engine speed will clear, and order will be restored to the world.

 

[enuff_zed]

You’ve done well mate.
Let’s hope this is the light at the end of the tunnel

 

[iamnotme]

You’ve done well mate.

Thanks. The only other fault is the DSC moaning about no engine speed. I wonder why :roll: I've pugged the crank in but I didn't want to try starting it again until I've repaired the injector loom, so fingers crossed that clears when it can see the speed.

Full custom exhaust fitted and dyno, then I'll be happy.

The irony is, I bought this car because of a spinal injury having a disc in my neck removed in 2021, which meant that riding my bikes was no longer realistic or safe. At the moment the car is trying it's best to cripple me more than riding a bike probably would :rofl:

 

[iamnotme]

Well it is all back to full health. Car starts and runs smoothly again.

Going for a test drive drive later, but hopefully it's sorted out the fluffiness lower down.

Great result. Well done for sticking with it.

 

[Mike6]

Well done, just shows what bodges people do with their cars. Out of interest how difficult was it to remove the inlet manifold. Are gaskets required. Cannot seem to find a quide anywhere.

Believe it or not the MAF extension was a professional job by the company that installed the supercharger in 2010.

The manifold uses o rings.

It isn’t too difficult to do tbh, especially when you’ve had it in and off a few times. There are a few videos on YouTube showing how to do it.

I marked the connectors as I went just so I’d know what was what, except the one that was already unplugged, and I couldn’t find a hole for until I looked at where the crank sensor was.
