1.6 / 2.0 FSI: the high pressure pump cam follower wears through

expensive

The high pressure fuel pump is driven by the camshaft through a cam follower. The early version got a flat follower (the `BAG` is the most affected), and it can wear through from as little as 60,000 km; if it holes, the camshaft lobe is damaged too, and the repair jumps to many times the cost. The later `BLF` got a roller follower, where it is rarer. Symptoms are hesitation, loss of power, hard starting, and a low fuel pressure fault code.

What to check

  • Ask whether the cam follower has ever been inspected: this is a routine check, and many people skip it
  • When cold, watch whether it cranks longer than usual
  • With a code reader look for fuel pressure faults

FSI direct injection: intake valve coking

expensive

With direct injection the fuel does not wash the intake valves: the petrol goes into the cylinder, not behind the valve. The oil mist and soot arriving through the EGR and the crankcase ventilation therefore build up on the valve stem and head, and from 80,000 to 100,000 km they restrict the flow. Symptoms are hesitation, loss of power, a rough cold start and misfire. It is not a part failure: it is a consequence of the design, and therefore it comes back. Cleaning (walnut or dry ice blasting) helps for a few tens of thousands of kilometres.

What to check

  • After a cold start watch the idle: rough running and shaking point to coked valves
  • Under load at low revs watch for hesitation
  • With a code reader look for per cylinder misfire (P0300 to P0304)

Information, not an expert opinion

We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.

  • A fault on the list does not mean the car you are looking at has it.
  • A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
  • You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
