During hard acceleration the high-pressure fuel pump fails. I've never had to replace this part on any other car that I have owned. When I research the part for this car, I reviewed many forums and articles complaining about the failure of the high-pressure fuel pump on the Mercedes c250 sport or similar chassis. The vehicle performs normally until there is hard acceleration; then the engine light comes on. This causes the car to lose acceleration power and slows the car down significant and can be dangerous especially if driving on a freeway or highway. The failure of the part has been reported to occur as early as 30k miles.

2012 C250 has a known defect with high pressure fuel pump. I personally have had an intermittent issue where vehicle will unpredictably stop working under heavy throttle and enter limp mode as the computer throws a fault code. This results in loss of power after the code making vehicle unpredictable and dangerous in passing situations. It leaves you stranded in the passing lane with oncoming traffic with a vehicle that will not accelerate. I have submitted a request multiple times with Mercedes benz corporate who has declined my submission. This issue has been ongoing since 2016. They have offered an extended warranty on the vehicle 10 years and 120,000 miles as they know there is a defect. It is dangerous and needs to be covered for all of the affected vehicles.

When accelerating to pass a vehicle the check engine light comes on and there is loss power. When this happens there is a huge potential of a crash. The car has to be shut off to try and reset this. When you are on the frwy this puts life at danger. The code is a p002 and if you research it Mercedes is aware of this and is most likely a defective high pressure fuel pump problem that needs replacing but there have been no recalls. I have looked it up on you tube and has been on ongoing issue with no recalls as of yet. I am taking my car to dealer on 11/15/2021 for this issue which they will charge me for even though its a safety issue

P0002 fuel volume regulator control circuit range/performance mercedes c250, if I'm experiencing a lack of power when I press the gas pedal and I'm getting a p0002 check engine light, there's a high probability that I will need a new hpfp high pressure fuel pump.

Auto only has 56k miles and fuel pump went out, auto stalled in city traffic 2 times in motion, no warning on issue unexpected due to low mileage on auto. No engine code till 200 miles after first stall, engine light finally came on, then second stall happened. Had code read p008a triggered. Took to personal mechanic for testing and repair. Had the system tested for the relay, the filter and it was the fuel pump. First occurrence 03/19/2019 second occurrence 03/23/19.
