Modulation should be as close to 50% as possible on a HOT engine.
Just started it?
Just started it?
Modulation is way out, should be 50% with the engine temperature at 95C. I have an easy way to adjust the modulation, PM me with an Email address if you would like the info.Just hooked up diagnostics again for engine, this is the screen, engine running, can someone explain the meanings please?
On starting, the engine is running as soon as I turn the key, is runs lovely & smooth & throttles nice, it smokes a little though.

Fuel flow out of range seems to crop up a lot. some say it's a worn FIP but I am not so sure. I have that fault on my project car, it has no effect on the cars performance. I will get to the bottom of the cause eventually
PM sent, thanks.
Flow out of range everytime I scan mine
The modulation is a must to set back to 50%
Yes your year of car will have 4 wheel ABS. Unplug the ABS ECU and see what happens. Modulation info will be sent this evening when I'm in my office.The more I think about it, I feel it MUST have something to do with the ABS module, since I believe it controls ALL the wheels.
As its one of the very last P38s made & DHSE model, I'm assuming it will have 4w TC ??
The way the lockup fades away after a short time suggests to me its pressure related.
Is there any way I can disable ABS/TC to try again & prove it?
I would be worried about the tyre ratings from the Tiguan, they may not be up to supporting the weight of a P38Lucky day, managed to source locally a set of 18" alloys from a guy just round the corner who was about to weigh them in!!
Can you believe, £50!!
Even luckier, managed to sell those awful 20" for a little less than I paid for the new tyres.
Even luckier still, I kept a brand new set of 18" alloys from a Tiguan I recently sold which had 20" originally, so the tyres went
straight on the RR!!
Woja fink??
Do you think I can pull the relevant fuses & relay instead? The glovebox is back now & it was a cow to set it to work right.Yes your year of car will have 4 wheel ABS. Unplug the ABS ECU and see what happens. Modulation info will be sent this evening when I'm in my office.
As said before, corrosion in the ABS ECU connector or a duff ECU. They do fail from time to time. I don't know, but you can probably look at live data from the ABS ECU with Nanocom, that might show where the problem lies.Pulled ABS fuses & ABS relay, took it for a quick run around the block, seemed to go fine, no sign of brakes or anything else binding, so what do I look for now? Nanocom tells me no faults.
The ABS ECU was removed, wiring connectors again like new, all coated with Stabilant, as well as trying a replacement ECU.As said before, corrosion in the ABS ECU connector or a duff ECU.

Certain failure modes of ECU's will not flag a fault.The ABS ECU was removed, wiring connectors again like new, all coated with Stabilant, as well as trying a replacement ECU.
If corrosion bad wiring bad or ECU duff, would not Nanocom flag up a fault??
Is it OK to drive with Nanocom connected?
