“This was all caused by not changing the air filters correctly,” explains Mark Shipman at AES as we look over the engine bay of the Mercedes C320 shown here that’s having its turbocharger replaced. He dismantles the induction pipework from the two air filter housings to the centrally mounted turbocharger and points to a couple of seals. Had the induction system been dismantled when replacing the air filters, the seals would have been inspected and replaced instead of getting damaged,
Tracing and fixing faults in electronic engine management systems breaking down and bits of them being sucked into the turbo, resulting in its destruction.
We have first-hand experience of the 2987cc V6 dieselwith the same engine and warned then about the potential perils of those induction seals. We also had to replace the turbo, but at the same time discovered that, if maintained, these Mercs can be reliable high-mileage family cars.
