Quick answer
Slough Car Servicing offers carbon cleaning for all makes and models at our workshop on the Deseronto Trading Estate. Work is carried out using quality parts and professional diagnostic equipment where required. Call 01753 439115 or WhatsApp 07393 580281. Located at St Mary's Road, Slough SL3 7EW.

If you drive an N47 BMW, a TFSI Audi or any modern direct-injection engine, carbon builds up on the intake valves because the fuel never washes them. The car gets sluggish, MPG drops, and eventually a misfire shows up. At Slough Car Servicing we walnut blast the intake clean.

How carbon cleaning is done

Most popular on the VAG 2.0 TFSI and 2.0 TDI range. We see plenty in from Burnham and Taplow. Done in a day on most engines. You'll feel it on the drive home.

We can scope-check the intake first with a borescope if you want to know how dirty yours actually is before committing.

"Highly recommend this garage. After contacting a few other garages who didn't want to take my car in for diagnostics, these guys were happy to help. They diagnosed and fixed an engine fuel leak issue professionally and efficiently. Great service and very reliable. I'll definitely use them again."

Carbon Cleaning. Frequently Asked Questions

How do I know if my engine needs carbon cleaning?+
Direct-injection cars (TFSI, TSI, TDI, EcoBoost, BMW N-series) build carbon on the intake valves from around 50-70k miles. Symptoms: rough cold idle, misfire on cylinder 1 or 4 first, dropped MPG, loss of low-end response. We can borescope the intake to confirm before any work.
Walnut blast vs chemical clean. What's the difference?+
Chemical cleans soften the carbon but rarely remove the baked-on layer. Walnut shell blasting physically removes it, valve by valve, with the intake off. The chemical route is cheaper and ineffective on the real problem.
Will it bring back lost MPG?+
Usually yes, plus the throttle response improves. Most customers feel it on the drive home.
How long does the job take?+
Most engines a full day. The intake has to come off, each valve blasted with the piston at TDC closed, then re-sealed properly.
Do you cover my area?+
Carbon cleans in regularly from Slough, Burnham, Taplow, Maidenhead, Gerrards Cross and Windsor.
