Last week we recieved this beautiful Mercedes Gla into our care for an ongoing performance and starting issue.
We read the fault data via the diagnostic machine and took the vehicle for a test drive whilst monitoring the live data. The car usually only goes out for short journeys which was really the root cause of its issues.
After a swift diagnosis we got to work at stripping down the front of the engine. As suspected, we found the intake manifold to be clogged up with carbon, causing the swirl flaps to be stuck in the open position.
We cleaned out various parts also found to be clogged with carbon from short journeys causing build up. Replacement intake manifold fitted and back together.
Fault data reset and the vehicle was back to full performance and now starts at the first turn of the key.
Despite the huge strip out required, we had the vehicle repaired and fully re assembled all within the day 😀
