w211 injector problems r they ""common fault"????

[WOK2]

hi
i am looking to buy a e class either 220.270.320 cdi, i have noticed most people i talk to with vehicles for sale say
"we have just had new injectors relaced"
is this a common fault, as according to my budget i am looking at probably "high mileage" cars approx 120000 miles

i heard they are very expensive to replace can anyone advise on


1. cost of replacement

2. what to look out for on a test drive to know whether injectors are in good state of repair or "out" or on the way out?

2. which model is most affected or which year im looking approx 53 reg


thankyou

They are about £200-£250 each fitted.. the injectors are under £150 to buy from Euro Car Parts and fitting is a couple of hours depending on how well they are stuck in!

Hi e220 is a bit under powered for the body size ,E320 best opition. When on test drive look out for vibration though car at 40-50 mph 1500 rpm ,gearbox / torque converter faults.Knocking from front when braking (front thrust arms).If you can get the chassis number you might be able to check with local mb dealer that all recalls have been carried out.Injectors as above ,worth checking merc price as now close to euros price.

all the above advice seconded. are the injectors a common fault? this is the common fail injection we are talkin about here...

I genuinely think the amount of money you save on fuel against a petrol you will need when they req repair.

Google mercedes cdi engine problems etc

Of course people will say i have done 20k with no issues, but then you buy it and it and it falls to pieces

I have owned a few diesels in my time and being a diesel mech what is annoying to me but cheap to fix is a major headache and expense to non diy/mech owners.

Ie last car ex manifold warping e bay and a few bolts, turbo cracking again the same, cost peanuts labour free, pay someone else £!

Dont get me wrong i miss the torque of a diesel but not the problems with modern diesels, especially when they have done a few miles, which is the case with nearly all my cars.

must agree here with lynall. the fuel savings of the cdi engines are often entirely offset by the repair costs. a good example might be an older car that travels 10,000miles a year. a couple of injectors and an alternator pulley will negate any fuel saving in a year. there are many parts that cost more to to replace on the cdi, some, like the alternator, are less obvious - these cost twice the price of the petrol engined equivalents. a great shame really as the cdi is a wonderful design with several achilles heels (if that is possible).
