ade1882 0 Posted November 3, 2009 I've noticed this is quite a common problem but am having no luck finding a solution. My corrado vr6 has an intermittent non starting problem. It randomly won't start some times. It doesn't turn over at all, I can leave it for 30mins try again and it'll turn over and start no probs.i have changed the ignition switch and changed relay 109. I can make this problem happen intentionly by leaving the lights and the blower on for 5 mins. but it isn't a flat battery problem because it can be left for a while and it will start when you go back to it again. I'm thinking of getting a new starter taking it to an auto electrian or to a mechanic. I've had the car for 4 years and it has been pretty much bullet proof then last month it cost me £2000 for brakes exhaust steering pump and rack. This is the only remaining issue I have and I'd love to get it fixed once and for all. Any Advice would be great. Quote Share this post Link to post Share on other sites
ade1882 0 Posted November 5, 2009 I was advised to change the ignition relay and went down to specialist cars(vw Aberdeen) to get one. they weren't sure which one it was and sold me 2 relays. relay 109 which i now think is the fuel pump relay because when I remove it the car turns over but does not fire. the other one is a relay with 100 on it but I can't find a relay in the footwell relay panel with 100 on it. It seems to be the same as relay numbered 18. can anyone advise me if this is the right relay with a different number on it or if this relay is located somewhere else or if any of these relays are the ignition relay?

fla 9 Posted November 5, 2009 109 is the ecu relay. Even if this fails the car will turn over as this is a direct circuit from the starter to the switch, via the immobiliser. All that happens if 109 fails is no spark and the injectors dont open. If it doesnt turn over at all it could be the starter solenoid that goosed. When you turn the ignition do you hear a click from the engine bay near the the starter? Try it with the bonnet open and a helper who can have a listen for you.

ade1882 0 Posted November 9, 2009 I have now bought myself a jump start battery booster pack and the corrado will start when I hook this up after it has it's non starting problem. As I said before the car doesn't turn over at all when it's not starting. I can leave it sitting for 5 mins with the heater and lights on and it won't turn over at all. I thought if the battery was a little low it would at least try to turn over. I did take it to kwik fit a couple of months ago and they said the battery was fine. I'm wondering if I should get a second opinion or maybe the battery is wrong for the car. Or could it be something else that is taking more power to start than it should. If it is just a dud battery this would be a relief. the markings on the battery thats in it are:- UNIPART Part No GBA3027, E480, A/hr62, R/C110. Quote Share this post Link to post Share on other sites
