DPF filter and FAP additive on the 1.6 HDI

DPF light flashing, loss of power, car in limp mode, oil level rising above maximum.

Uzrok /On the 1.6 HDI (DV6) the DPF clogs quickly if the car is driven only in town. Peugeot also uses a FAP additive that can run out without the owner knowing. Failed regenerations dilute the engine oil with fuel - and that is a serious risk for the bearings.

Popravka /We diagnose DPF state and check the additive level. As needed we force a regeneration, clean the filter or top up the FAP additive. If the oil is fuel-diluted we change the oil immediately before anything else.

Timing belt and water pump on the 1.6 HDI

Moisture around the timing cover, intermittent knocking, loss of coolant, slow engine warm-up.

Uzrok /The 1.6 HDI DV6 has a strict timing belt interval that must be respected together with the water pump. The water pump often gives up first, and when it leaks it risks the belt. A snapped belt means valves hit the pistons.

Popravka /We replace the timing belt together with the water pump, tensioners and rollers as a kit. We recommend not waiting until the last moment - the gap between a scheduled replacement and the repair after a snap is enormous.

EGR valve and intake clogging

Loss of power, check engine light, engine stalling at idle, black smoke from the exhaust.

Uzrok /The EGR valve on the 1.6 HDI clogs with soot and the intake manifold fills with carbon deposits. Short city trips significantly speed this up. It is one of the most common reasons a Peugeot ends up on our diagnostic ramp.

Popravka /We remove and mechanically clean the EGR valve and, if needed, the intake. If the valve has failed, we replace it. After cleaning the engine runs like new - provided you act in time next time as well.

Turbocharger on the 1.6 HDI (PSA)

Loss of power above 2500 rpm, whistling, blue smoke, oil in the intercooler, rising oil consumption.

Uzrok /The DV6 turbo vacuum actuator wears out, and the bearings suffer if oil changes are neglected. The oil feed line to the turbo can clog with deposits - it is not rare to see an engine lose its turbo precisely because of old oil.

Popravka /An experienced mechanic can replace just the actuator instead of the whole turbo if the fault is caught early. If the bearing is already damaged, it is rebuild or replace. At the same time we clean the oil feed lines and recommend shorter service intervals.

Injector copper washers

Characteristic hissing sound from the engine, black deposits around the injectors, exhaust smell from under the hood.

Uzrok /Copper washers under the injectors leak combustion gases back into the engine bay. The dark deposits around the injectors are a dead giveaway. Ignoring it lets soot damage the injector seat in the cylinder head, and the repair becomes significantly more expensive.

Popravka /We remove the injectors, clean the seats and fit new copper washers. If the injectors themselves are damaged, we send them for specialist testing. Acting early matters - the cost of repair grows sharply with delay.

BSI module and parasitic battery drain

Battery dead in the morning even though the car is otherwise fine, strange warnings on the cluster, electronics behaving oddly, lights doing things on their own.

Uzrok /The BSI (Built-in Systems Interface) is the central computer of the car and it hates moisture. When water enters the BSI module under the seat or passenger footwell, the module draws current uncontrollably. The result - the battery dies overnight.

Popravka /We locate and fix the source of the water ingress first. Then we diagnose the BSI module and dry or replace it as needed. Without fixing the moisture, any electronic repair is only temporary.
