Hello guys. Car is 1.9CDTi 150bhp z19dth and I think I have got a very serious problem. Long story so please bear with me.
Driving on a country road last Sat, EML came on the dash but car was still moving okay. I had cleaned out the EGR and boost sensor on Fri and thought probably there was a loose connection somewhere. Pulled up to check and on closer examination, found the swirl linkage bar http://www.vectra-c.com/forum/showth...ant-for-please and thought that was the problem. Turned around back home and car started losing power intermitently, not going over 2k rpm and sometimes power was restored.
Put it on code reader and got p242f and p2279 (I cleared them) which I understand is likely blocked dpf. I did the rubber washer fix and fitted the linkage on Monday. Took it for a test drive and was still losing power and fault codes returned but while driving, there was a burning rubber smell (assumed dpf regen). Saturation on reader showed 68%.
Tried to take it for a long drive on Wednesday to see if things will clear up but car lost power and turned itself off after loads of black smoke from exhaust. Emission light came on and code was p2452-0F (Particulate filter pressure sensor pressure (95Kpa) not plausible with barometric pressure (101Kpa)). Eventually got it started after loads of tries but it kept turning off if I tried driving and was towed home by RAC.
I cleaned up the throttle body, inlet manifold (as far as I could reach) and check the electrical part of the throttle today. Started up the car and the rev was not going more than 2200rpm. I held down the gas pedal and observed a lot of continuous black soot (smoke) coming from the exhaust. After about 7mins minutes of holding down the pedal, there was loud hissing sound like gas escaping from a cylinder under high pressure. Switched off the engine and looked around the engine area to see if there is anything unusual but there was nothing. Only code showing now is the p2279.
Went back to the car after like 2hrs to check again and decided to check the engine oil level. To my surprise, the level was way high up. That is unusual so what have I knackered? Are the turbo and the dpf gone?
I wish to sort this out myself without involving the dealers if possible. Any help will be appreciated. Once again, sorry for the long story.
