shocking news after service...
 

I just took my 2005 E53 3.0D with 74,000km for servicing and the official stealer told me that one of the spark plug (injector?) units had to be replaced and would cost me USD 600. He actually advised me to have all 6 replaced in anticipation of failure of the other 5. Is this for real? Is something like this normal after only 74,000km? Please advise I really feel desperate right now.

Thanks!

Replace just the faulty unit.Following the dealer's logic you have to replace everything,the whole vehicle eventually.

:rofl:

Think I would take it else where especially if he did infact call it a spark plug.

If the dealer actually called it a spark plug, then run away very quickly, because your diesel doesn't have spark plugs. If he called it an injector, then fine. If he called it a glow plug, then that is different again.

It seems early (in terms of mileage) but injectors can fail. There should be a diagnostic code that leads the dealer to conclude that an injector needs replacement, either because it is leaking, or because the spray pattern is not correct.

The price is high. You can get another quote for the job to decide if you want to the dealer to do it, or an independent garage that is familiar with BMWs.

Some things that cause a bad injector could cause the same problem in other injectors. It goes back to the codes, though.

Another poster with a 3.0d could comment on how common injector failures are at five years.

Good luck.

Fuel injector issues after 5 years or 80,000 kms not common at all.Its common ,thought,for the Common Rail fuel pressure sensor to fail.
As the guys are saying,you have to determine exactly what you are being quoted for?Glow plug or fuel injector?Error code that was diagnosed would also be useful.
If its fuel injectors ,then you can just replace them individually.If its glow plugs,then we here at the dealer always replace all 6.:)
Lets us know when you have more information.

you probably need a coilpack. get one from bavauto

Diesel engines are 'Compression Ignition' engines and have no ignition circuitry, coilpacks or sparkplugs. The heat in the compressed induction charge air when the piston reaches top dead centre is above the spontaneous combustion temperature of the diesel fuel and hence no other ignition system being needed. It's what causes the characteristic diesel knock.

Glowplugs are only used for a few seconds to provide enough heat initially when the air temperature is below 5C. Once running, a diesel engine is normally only stopped by cutting off the fuel supply, or on much older industrial engines by keeping the valved open to prevent compression.

$600 for a glowplug is way over the top! Glow plugs are about $25 each.

Injectors are about $200 each, cheaper if you have a remanufactured one, but only by about $40.

Thought it was 3.0 v6

Hey,come on,not a V6 thing,please.:rofl:
