How VW and Audi 2.0t TSI High Pressure Fuel Pumps Fail (HPFP) ~ Video
Next up in our series on failing Volkswagen parts, we are looking at the 2.0t TSI High Pressure Fuel Pump failure. I will be using HPFP for short. This is a failure that I was replacing regularly a few years ago. Today we don’t see the failure rate that we did, but they come in from time to time. We have had cars driven in with a bad HPFP, as well as towed in. This is a part failure that may leave you stranded. The good thing is that no top end damage is done to the engine. The BPY 2.0t is a much more catastrophic failure. I did a video on BPY Cam follower and HPFP failure if you want to learn more.

Last time you had talked about HPFPs, I had made a comment about the broken pintle you mentioned in this video. An important step in replacement is to make sure the cam lobe is at a low spot, not a peak where the roller rides. If its at a high spot, you compress the spring as you tighten the bolts and put extra load on the pintle and can break them. Also, you want to tighten the bolts for the pump evenly for the same reason, to not load that pintle unevenly. I have seen quite a few brand new pumps come in to the shop with fuel pressure issues that had broken pintles when I pulled the pump.
Thanks for the head up on it James. This is the first one I have seen break. I had a chat with the tech. He is a pretty reliable guy. He even mentioned that’s how he tightened it.
if you’re careful, can you install the HPFP with having to make sure the cam lobe is at a low spot.
Charles, Great and timely video. This very afternoon, the EPC light on my 2012 Tiguan came on and it lost nearly all power. We were able to limp it home where I scanned it for faults. VCDS showed a P0087 code for fuel rail pressure too low. When watching block 140, the fuel pressure was completely flat at 8.3 bar.
It is a scary coincidence that you posted this video this morning and our Tiguan had the issue this afternoon!
Keep up the good work with the informative and entertaining videos.
Thanks Scott! I hate that this happened to you today. I hope I didn’t jinx ya. 😉
Wow Charles, you obviously hold great power! Must be that promotion.
I have a VW Jetta gli 2010 tsi few days ago began to have a fault, the time to move from a stoplight or pass a stop and step on the gas vigorously car loses power and shuts down and displays the fault code P 2293 concerning the fuel pressure could damage HPFP?
Did you ever find the solution to the problem ?
Charles, can you recommend an updated pump that may be out there that isn’t prone to the pintle breaking?
Trying to figure out a path to take.
P2177 lean at part throttle.
I have a tune, different diverter valve, test pipe, catch can, intercooler.
I’ve replaced the following in part because it was needed and hoping it would help.
CHRA, valve cover, cleaned intake valves and replaced intake gasket, 2 cans of BG44K currently, swapped front o2 sensor and MAF with no change. Lift pump and filter due to 12555 (i think thats the code)
I’m thinking HPFP but the data says its fine and under 5bar difference allll the time. Other option is pressure sensor 247. Hoping someone may have some insight.
Hey! Could the HPFP cause my EPC light to come on?
I have been getting an on and off HPFP and EPC seeming to come on at the same time. Coincidence?
Should there be power to the HPFP solenoid when the key is on?
