Ignition problems

Followers

November 19, 20187 yr

I have been tasked with trying to sort out a problem on a c3 100 quattro turbo (MC engine).It has previously had an immobiliser fitted and that has been now removed.The problem is that I can only get an ignition spark at the king lead out of the coil for about 1 or 2 seconds,then it disappears.

I have done as many checks as I can on coil,rpm pickup,crank position sensor,dizzy,and have pinned out as many connections back to the ecu from all these units as I can.I guess all the systems must work to give a spark,but why does it bugger off like that?

Any ideas gratefully received before I send the ecu off for testing.

Many thanks, Dave

Bedders · May 27May 27

HI All, Can you help? My faithful and reliable twenty year old A4 2.0 TDI has developed a few issues. Lack of power in cruise mode going up hills and major juddering when I am lead footed (not often, but when i need to get out of trouble) which causes the engine to vibrate and judder. The car has full Audi servicing for the first 16 years of its life and more recently local garages in the last fours years and has 126,000 miles on the clock. ( i bought it for long distance driving but was made r

Hydraulic whine when low speed engine idle a/c on

Optimus · 6 hours ago6 hr

I’d thought I’d check in on this as my tdi 40 is now coming up to 3 years old. My a/c is always on during summer without fail. This is the first time I’ve ever heard this, this loud. I normally can mainly hear it in the cabin when turning steering wheel on full lock, you know that a/c moan/groan sound. it sounds like the condenser fan blowing, picks up pitch and rhythm with rev counter. So I’m going to assume it’s probably belt related. Anyone experienced this? I’ve booked it in but typical m

Having problems working out my fuel tank capacity -

Steve132 · June 13Jun 13

Hello I am a new Audi owner and have a A6 40tfsi C8 Facelift Sport Saloon. The car has been everything I hoped it would be -quiet and smooth on the road with enough power to keep me happy in retired life. When I first received the car it had a quarter tank so when it reached only 30 miles of fuel left I filled it up to the brim but could only fill 53 Litres. I have again run the car to show only 30 miles remaining and again can only fill 53 Litres before the tank is full I have checked th

Rough idle on cold start

nitch · 19 hours ago19 hr

Hello, I've got a 2015 3.0 BiTdi Allroad. I get a rough idle when then engine is cold. Feels like a cylinder misfiring. Once up to temp, it's fine. The car has been used a bit more for short journeys than I'd have liked. There are no error codes on VCDS. I changed all the glow plugs recently as one had gone down. Could it be some carbon build-up? Is there anything I should be looking at in VCDS to help diagnose the issue? If it is carbon, what needs removing and cleaning? Thanks

Paddington · Thursday at 01:56 PM1 day

Hi folks, looking for a bit of knowledge to help me understand a start/stop niggle with my 2026 model A3 S Line 35 petrol. The engine has suddenly taken to cutting out without warning. Doing so at 70 mph on the motorway was terrifying lucky I managed to dip the clutch before everything locked up. It has done this at various speeds since that first experience. I've been back to the main dealer who advised do NOT turn the stop/start system off and having done so touch wood no more cutting out inci

Oil usage on 3L A6 2014

Lhotse · 10 hours ago10 hr

Hello all. I have recently changed my 2012 A6 for a 2014 as above. The car is in nice condition but it is using a bit of oil. I have done about 400 miles in it since Tuesday this week and already the oil level has dropped quite a bit. My 2012 Audi did not have this problem . Is it because it is a 3L V6 or does this have a potential oil problem? Many thanks

New Rear Springs

Ian Newman · May 5May 5

Hi Team, Can you help please help. Just had new rear springs fitted but the result isn’t what I or the local garage expected. Supplier has checked the colour code on original spring and has advised, correct springs have been supplied. I don’t remember seeing the seat area where the bottom of the broken spring sat but the seats where the new springs sit appear incorrect but they have to be there. Car sitting approx. 30mm too high, 264mm springs supplied. Las

Jake1991 · Thursday at 09:33 AM1 day

Good morning I would be eternally grateful if anybody can help with a very annoying issue I have with the air blowers. When I set the blowers to the dashboard vents, air comes out of the passenger side and middle vents but not the drivers. Instead the air comes through the footwell vent on the drivers side and not the dashboard vent. To make it even more confusing, when I set the blowers to to the footwell it stops coming out of the drivers side and only comes out the passenger side. I assume it

Boot opens when drivers door opened

Raj A · Thursday at 07:59 PM1 day

2026 SQ8 Often my boot opens when I open the drivers door. Sometimes I find it open for no reason even when the key is not on my person. Today I found the front passenger window opened and the roof tilted about 10 minutes after arriving home when they were definitely closed. Has anyone else had these issues? Any ideas? 7e84e0e21d83473aa1ec13f4f11b59da05052026_111657am.mp4
