Carbon Clean

[Mercedes Traitor]

So today the car had an internal deep clean!

After changing all three engine mounts the Avant is still slightly lumpy on idle, there have been many posts on here suggesting what to check and what to clean.

So after 1hr internet research I booked a clean through enginecarbonclean.com. as a starting point.

The Bucks area engineer Gary arrived this morning at work and set to work removing 120,000 miles of carbon build up, in his words -
Why is carbon harmful to my engine?

Allowing carbon to build-up over time will cause:

Sluggishness

Lumpy idle

Smoking from the exhaust

Emission levels too high (failed MOT)

Sticking EGR valves and turbos

DPF warning light illuminated

Declining MPG

So an hour and a half later all done!, a couple of faults found regarding glowplugs but otherwise a clean bill of health.

Gary suggested take the long way home and get the engine hot as there will still be elements in the dpf, so I obliged!!

After 30 years in the Motor Trade I was a sceptic, but the cost is minimal and it certainly wasnt going to do any harm.

So was it worth it ?
Most definitely! Amazed by the improvement in power and smoothness literally feels like a different car.

I will update in due course if mpg is better, but felt compelled to let you all know that was probably best £99 spent on the car so far.

Why don't you just delete your EGR valve, inject Mr Muscle oven cleaner into the exhaust side of the turbo at every service and mix 2 stroke oil with your diesel on each fill up and save yourself money in the long run?

Would deleting the EGR not affect the DPF and regen, usually these are tied together?

Probably so, if you have a DPF.
I have one of the last B7s not to have one. 2.0tdi BRE 140 (remapped to 180).
The BRD (180) has a DPF and later B8 diesel engines too I believe
