For the last 6 months my Galaxy has been very slow on accelerating and top speed of about 75. It really caused problems in Wales !!!! I have changed the MAF sensor twice - Fuel filter - air and oil filters - and checked intercooler and as many pipes as I could find. The symptons were: acceleration very slow of the mark until hit 2000 rpm and turbo kicked in and then kicked out straight away. I eventually took it to a garage and they diagnosed sticking variable vanes on the turbo. Ford wanted £1500 for a new one - so sent it off to Turbo company who confirmed diagnosis. Turbo rebuilt for £200 and fully tested. Excellent service. Refitted and hoping for a major change in performance - BUT it is slightly better but top speed now only 80mph. I know the turbo is producing boost. I have full code read and it shows no faults? There is no smoke from exhaust. The only sympton I can describe is that the engine feels very rough. between 1000 and 1500 rpm the engine shakes the car - similar to one cylinder not firing.
Any suggestions most welcome as I am at my tether.....

Sounds like you've tried a fair few remedies. Do you know of any local diesel engine or VW specialists (being as its a VAG engine in there) and see if they can take a look without dealer prices. What bhp/PS version of the TDi have you got? I had a 2002 Bora 130 TDi and got 51mpg out of it over 105000 miles. It went like a rocket and pulled like a train even in 6th. Brilliant engine.

hi - it is the 115 bhp version. I drove it today and had a friend on board. He commented it felt as if a cylinder was not firing. At low revs it vibrates a lot. I am wondering if a injector is blocked - that would also reduce turbo boost a lot I would have thought. Local garage could only find turbo issue.

Does sound like one of the injector units is duff. I would get it to a Diesel specialist - this sort of thing is beyond the capabilities of most local garages - you need equipment, experience and trained technicians. Poke-and-hope is an expensive way to go about fixing a modern Diesel.

Get it to a specialist. They should pick up on fault codes too. If it was only acceleration with low revs (reluctance to rev) then could it be the EGR valve.
|
|
Hi - i have seen articles about the EGR valve. Where is this and can I test it in any way?

tookadvice and car going into diesel injection specialist tomorrow - have all the proper diagnostics and years of knowledge. Mind you their eyes rolled up when they found out it was a Galaxy PD engine.......
what this space....

It's a VW engine as used in many VW's, Audis, Seats Skodas as well as the Ford Galaxy / VW Sharan / Seat Alhambra, might be worth going to a VW specialist.

I have got my Galaxy back from the Diesel specialist. Well - the engine is in tip top condition EXCEPT - the MAF sensor is sending an incorrect reading to the ECU. Apparently this will not show as a code fault because it IS sending a signal. Apparently the ECU thinks the engine is getting about a third of the air it is actually getting and therefore reduces diesel delivery. So the engine lacks power! engine lacks power - turbo boost reduced etc etc etc. The MAF is not a genuine Ford part so I am going to try a genuine one. Mechanic warned against non original MAF sensors as "you never know where they were made" !!

New MAF fitted and the difference is amazing.... lesson learnt - an ordinary code read may not detect any fault - you need to check the actual live reading and see that it raises and throttle pressed. Mine was sendign a constant reading regardless of throttle.

There's an interesting article in this months Car Mechanics about a Galaxy with a engine problem, They tried replacing a sensor but it didn't fix it so they called in a specialist who diagnosed a faulty turbo with stuck vanes.

Buy a Citroen and get to know the local GSF staff better...
