    Unhappy Vauxhall Zafira 2.0 DTI Loss of power.

    Hi All,

    I own a Zafira 2.o DTI 54 reg, and I have been experiencing problems with loss of power.

    About a month ago I was driving on the by pass at 70mph with no problems until I got to the end at the roundabout. I slowed down gave way to traffic but when I went to zoom off the power died almost like the turbo had gone! I drove home (slowly) thinking I'd have to get a new turbo, but the next day I started the car set off and it was back to normal no probs!! Anyway I decided to take the car to garage to do diagnostic test. That showed no fault codes?????

    One month later went out for family drive and on way home loss of power again exceleration poor upto 2000 revs really poor on hills and hasn't improved this time, sounds like its cold a louder diesel rattle, and on exceleration sounds sometimes like its going to improve then doesn't. I took the car back to garage, they did diagnostic which showed no fault codes but mechanic said there was faulty connection on heater plugs, so I had new set of them, Loss of power still a problem . Mechanic suggested full service so I went ahead with that....Still feels like no turbo.
    Feeling desperate with not many pennies for a big vauxhall garage, I took car to a friends garage, he said there was a fault showing on fuel pump, malfunction!!

    Please if anyone had same problem could you send me some advice and if so does it sound expensive as I think I need to visit vauxhall with this one, maybe doing more damage driving round in it. Thanks for reading

    This problem has been covered here several times before - EGR valve.

    1. What is this mechanism that stops and starts the car?
    2. The spanner light being on means an emissions fault has occurred.
    3. A fault code will be stored in the engine management computer. A diagnostic at any decent garage will tell you what the code is and probably the faulty component.
    4. As MrDanno said earlier this could well be the EGR (exhaust gas recirculation valve) stuck with carbon build up or failed motor.
    5. It could also be carbonned up inlet flap valves.
    6. Black smoke is very often a sign of a failed EGR valve and also fits with the symptoms you have given in your original post.

    Have the car put on a diagnostic scanner.

    Well MrDanno and Hometune.....it seems you were both right I was dreading the diagnosis!! Took car back to Vauxhall VERY SLOWLY I might add!! and this morning they informed me it would be 530!!!!!

    I have read so many posts on forums that even EGR replacement didn't cure things...is it time to trade this car in or what!!! Mr Danno and Hometune do you have advise for me???? Thanks Cathy

    Well, the quoted price is quite large! An aftermarket EGR valve will cost about 150 and takes around 30 mins to replace. But, as you have discovered, this does not always cure this fault because the flap valves may also be caked up. Perhaps the price quoted includes replacing them? If so, then the fault will almost certainly be cured and for a long time unless you only do school runs, local journeys etc when the carbon build up will start all over again and made worse if you use cheap supermarket diesel and poor grade oil in the engine.

    I am biased against all Vauxhall cars as I have found them to be the most unreliable on the road, narrowly beating Renault. I never advise any of my customers to buy a Vauxhall of any type, van or car, as there are other better and much more reliable cars out there. But the decision is yours and if you like the car and the mileage is not excessive, maybe let Vauxhall do the work. It will be covered by their warranty for 12 months so if it does not fix the fault, take it back and have them fix it free of charge.

    Yeah I was really shocked with the cost, but I can't do the work myself and my local garage is useless, that's why I decided to go to vauxhall.

    Most of my Journeys are round town and school runs!!! Maybe I need to give it a good run every week, would that help? The diesel was replaced by local garage, when I had a full service, which I have to admit was the first FULL service in about 4 years. oops

    My hubby worked for Vauxhall as an apprentice years and years ago before computers, so I think thats why we got one..not that as anything to do with it now!!

    I do like the car though and its a good size for the family at the moment.
    So the part will be under warranty for 12 months? Thats a little bit of good news then .. I suppose

    Thanks so much for your reply Home tune
