Vid is unfortunately done with mobile but it's when is playing up. I'm picking up tomorrow some diagnostic tool and I'll start probing it from ecu side. I'll keep you posted.

If sensors etc look to be good don't overlook compression test & fuel pressure and injector relative test or bench test . Does it smell like it over fueling and did plugs/plug show sign of over fueling.

When it doesn't start it stinks of fuel and when I try to drive it it pops and bangs very hard and when I've replaced plugs it flooded them straight away. I just need to organise myself bloody fuel pressure test as we're more of commercial vehicle specialists/Mercedes and those things usually run on diesel... Oh and need to trace this clamp you've mentioned.

Were you able to test the coolant temp sensor yet mate?

My mate had a similar problem with his Evo, turned out when we shone a torch down the cylinders the head gasket had gone and he was getting water into one of the cylinders and causing it to run like a sack of poop, like mr b says a compression test is a good idea

Ha,sorry man, I'm sure it will just be a dodgy indicator bulb or windscreen wiper blade causing the problem Razz

Well took out my ecu today pins are intact but can check it inside for any water ingress cos all screw are rounding

Little update.
Compression: test 165psi across all 4 cylinders cheers
I've managed to borrow Bluetooth consult lead I believe Mr Guest was selling them and got Ndsi for android.
Plugged it in got data coolant temp 22 deg maf 1.5v (circa) on cold idle and going up as its warming up, everything else looks ok.
Self diagnosis - code 21 (ignition signal) recorded 35 times and code 11 recorded 1 time ( cam sensor - I've disconnected it when cleaning cylinders from fuel). What puzzles me is why the hell it didn't show up on blink codes? But at least it makes bit of a sense now.
I've found diagnostic procedure
https://drive.google.com/file/d/0B7Ub2apq5-pfTi1NYzJNVmxfTTQ/view
And I'll start going through it tomorrow wish me luck as I love wirings!! suicide suicide

Ignition code on mine was the coil/amp next to the dizzy. The plug had slipped off slightly and kept happening.
One time the plug came off and stalled the car in traffic.
I cable tied it in place and no problem since.

Mine was plugged in ok I'll be tracing wires there now I guess. But at least I'know where to start now... Need to get myself bloody consult cable...

Ignition amplifier knackered?, seem to remember a thread on the 'other site' regarding this and someone relocated away from heat and vibration, just a thought mate.

I've replaced amplifier with known good one and it didn't make a difference but thinking about it now the car might have been flooded.... (I'm bit of a tit sometimes lol) So tonight I'll replace it again make sure that is mot flooded and give it a go if not I'll get my multi-meter out...

Is little bit in petes 'power problem' thread referring to the power transistor reliability and relocating plus keeping a spare handy . if you ain't touch it in last decade it likely original so old and would tie in with your symptoms , parts changing generally proves very little and often makes diagnosis worse as start crossing off components that still likely faulty directly or indirectly .
Would be sweet easy test/fix if is and put you out your misery and back on the road making noise lol .

I know what you mean B but sometimes change something for known good one is quickest way to eliminate faulty component (I know not always and let say provisionally). I won't lie component testing sometimes does present trouble especially when I haven't got too much data or do my research first... I can diagnose brand new Audis but not 25 year old Nissan piss taker

Yeh I know what you mean, I have fair few stocked parts for quick swap out but easy bites you in butt,
had times when swap out seems fix issue but it simply as disturbed a bad harness and so forth .
Fingers crossed it ends with a easy fix. the old consult 1 cables are super handy and everyrone should have that or the bluetooth/usb one . have fun and some luck mr gostek ... don't think I actually ever worked on an audi .

Audis are nice and easy used to work on them for 5 or so years ( especially 1995 till 2008 models before euro 5 emissions). Now I'm working for Mercedes specialists mostly Sprinters but anything goes. I've had Sl 55 amg for suspension faults supercharger fault etc atm I'm in process of tearing apart 2016 Gle just to replace some tiny battery I'll get some photos tomorrow. But I can say only one thing about Mercs they are over complicated over engineered pieces of shit and I'd rather be changing clutches on Pulsar whole day long or put pins in my eyelids.... They're so bad to work on but that just me lol!

Well guess who got lightly fried ecu....



Pin no 17 which is maf and pin no 21 throttle position sensor. Don't know what else cos I can't undo screws underneath.

Now to find the cause mate

Assuming there's no other damage that looks repairable with a couple of soldered jumper wires. Had almost exactly the same thing happen on my last R, due to dodgy wiring in the maf plug shorting out and frying ecu. Soldered ecu, replaced maf plug and she was good to go Smile
