Hi Mazi,
So sorry, but not suprised to hear that your Espace is going the way of many MK 4's
I can offer very little advice other than search this forum for all issues with the 2.2Dci MK4, and be ready for what you will find.
I guess the car is above 50,000 miles?
Could you give me a little more info and I can try and predict what comes next after your first bill!
It will not help with the current issue you are unfortunatley experiencing, but fore warned is fore-warned.
to get you in the right frame of mind:
I guess after our Espace , 2004 Dci 2.2 "let go" this week I can honestly say the ONLY thing that did not go wrong over it's 70,000 miles, WAS the egr valve.
Lets see what your mechanic can find, fingers crossed.
Our Car:
£10,000 investment when bought, my Wifes "dream car".
5 years (60,000 miles) hassle free, than all hell breaks loose.
(Timing belt change at 65,000 expected for age of car, no issues there)
Inlet Maifold, (known issue) blows at 65,000 £800.00 & 1 week off the road.
68,500 miles, turbo lets go, 2 weeks & £1,300 to fix.
4 weeks after turbo, balance shafts break up, engine condemed, £5,300 to replace, car worth scrap value.
Negative equity (after expected depreciation) stands us at:
£3,400 - market value of the car (running)
£1,300 - wasted on turbo 4 weeks ago.
Please let me know how you go, I do hope that it is cheap to fix..
And I am sure the guys on here will give you plenty of pointers, it is a good source of info.
