the astra ive just got has a small prob, the engine managment light keeps coming on and it gets sluggish, ive disconnected the wastegate solenoid and it drives sluggish and the engine managment light comes on, so ive changed the solenoid with a known good one and it still does it

 

anyone got any ideas on what could cause this

The fact it was free.......probs gubbed?

My parents used to have an astra estate and the light came on now and then with that but it drove fine....just got the light over ridden.lol

it still drives, its just sluggish as if the turbo aint working properly

Poss air flow meter mate, done a few vauxhalls with symptoms like you have and has been those each time.

cheers bud, ive had a quick google and it does come up with airflow meter, dont have a fee good one do ya lol

Exactly the same fault as my mate had - believe it or not he found the solution was LOW engine oil!!! have you checked that?

hmmm, no, havent driven it far and im doing a service this week, will check in the morn

 

cheers

Sorry mate I dont as each ones I have changed have been goosed, you would need one with the same number on it as you have now, I got one for a corsa brand new off ebay for £30 delivered if thats any help bud.

cheers, will look into it

If in doubt mate, take the bulb out!

i have a 1.7dti astra with that problem, lights constantly on, unless i brake really hard, then it comes back on when i accelerate (well, it doesnt accelerate, but ya know what i mean. If i go on the motorway and floor it, when the revs get to about 3500 in 5th, the turbo kicks in and its fine until i turn the ignition off, then back to no turbo. Tried oil level, all connectors, had it plugged in to an AA laptop, no joy. Common fault i believe. Let me know how u get on mate.

good luck.

cheers

Wont stop the sluggishness though! :mac1:

Egr fault usually on astras.Valve stays open so boost from turbo dumps out the exhaust.

thats the 2l dti engine causing that! :tongue:

I had the egr off mine, it was covered in thick black crap. Cleaned it, free'd it up, put it back on and no difference at all.There is a little valve near the egr with a small vac pipe joining them together, it has an electrical connector on it aswell. thought that could be broke. What you suggest? New egr?

cheers

The solenoid you mentioned actuates the egr valve.They too can play up.To eliminate the egr valve.Where it connects back into the inlet manifold make up a gasket from a piece of coke can so it blocks off the system.Then try it.
