Is your Mercedes C-Class showing AdBlue system errors, NOx sensor faults, or the dreaded SCR warning? You’re not alone. The AdBlue (SCR) system fitted to many C-Class models is well known for faults that lead to expensive repairs and vehicles dropping into limp mode.
At Adblue Fix, we specialise in Mercedes C-Class AdBlue delete and NOx sensor removal. With over 10 years of experience, more than 500 five-star reviews, and both a Slough workshop and mobile service across England, we are the UK’s trusted choice for AdBlue solutions.
Why C-Class Owners Choose AdBlue Delete
The Mercedes C-Class is a premium executive car, but its AdBlue system is one of its weakest points. Instead of reliability, it often causes stress, costly dealer visits, and unexpected breakdowns.
Common Mercedes C-Class AdBlue issues include:
-
Dashboard warning: “No engine start in 700 miles – AdBlue fault.”
-
Repeated NOx sensor failures.
-
Fault codes such as P20E8, P207F, P229F.
-
Expensive dealer repair costs.
-
Cars going into limp mode and losing performance.
Our AdBlue delete service provides a permanent fix:
✅ No more AdBlue refills.
✅ No more limp mode or loss of power.
✅ No more fault codes or dashboard warnings.
Mercedes C-Class AdBlue & NOx Fault Codes We Remove
Here are the most frequent codes we permanently remove for C-Class owners:
-
P20E8 – Reductant Pressure Too Low
-
P207F – Reductant Quality Performance
-
P229F – NOx Sensor 2 Bank 1 Performance
