Thanks , I noticed the smell the day after I collected it .Its back at the garage ,they have replaced all the seals,I was supposed to get it back Saturday but number 2 is still leaking passed the new seal .Interestingly I think number 2 injector had previously been replaced as it looked new .
So further work to be done .
They also replaced the brake vacuum sensor as the stop start was not working .
The fault was cleared but the stop start still is not working .
The cleaned area .
