Greetings all just after some advise as ive found clashing info on the net and i work away and have not got my manual with me. Firstly is a 2001 320d se tourer turbo charged.if so how can you check if the turbo,s buggered.reason i ask,our lass has the 2002 td compact and i can hear the turbo on that and the fuel range indicator stays above 50mpg with light feathering of the throttle and returns 56mpg where as i have to be persuading on the throttle to promote forward motion if you get my drift and i return 47mpg.Obviously i will be changing oil,filter,fuel filter,and pollen filters at the weekend. Secondly the cars done 145000 miles with bmw company car history for the first 6 years(100000 miles) but the last 5 years there is didly squat history.how much punishment can these engines take if not looked after(could well have been very well looked after but just no history however) Thirdly would you advise doing DIY servicing if competent at this sort of millage or would you always recommend BMW servicing. Looking forward to your input.Best regards Mal...
