Failed High-Pressure Fuel Pump (HPFP) - Checklist: What to Do After a Pump Failure
We commonly see failed High-Pressure Fuel Pump (HPFP) on modern Common Rail Diesel Engines resulting in a tangled web of issues, expensive repairs and headaches. The most common symptons are poor startup or a lack of power (especially under hard acceleration).99% of the time HPFP failure is most likely due to internal wear or metal-on-metal contact which often sends metal particles/shavings, also known as "swarf" throughout the entire fuel system. If these contaminants are not removed completely

Silverstone GP - Britcar Trophy - 13th March 2022
We had an early start to the 2022 racing season, as we made a one off entry to the Britcar Endurance Trophy race at Silverstone on the GP Circuit.
With it being in March, it gives us another month to fully prepare for the first rounds of both the Turismo-X Racing Championship and the 750MC Club Enduro Championship, which we are competing for the whole season. All the details and dates for those series can be found on the Darkside Motorsport Page.
A layout of Silverstone is below. We get

Brands Hatch Indy - MSV SuperCup - 12th September
The next round of the SuperCup, took us all the way down South to Brands Hatch, on the short Indy Circuit.
With a busy schedule outside of racing, we were not able to do any testing before the race, which wouldn't have been much of a problem had we not being having the usual Golf nightmares!
The DSG box started causing issues on Wednesday night, sticking in gears. We figured it was a wiring or solenoid issue, both of which we had lost interest in trying to diagnose after countless hours trying

Silverstone GP - MSV SuperCup and Focus Cup - 15th-16th August
With only one week between our MSV Trackday Championship and EnduroKA success at Oulton Park (which you can read about here) and the next round of the SuperCup, we needed to get the car ready quickly, especially after we found a few niggles that we know would haunt us if we didn't get them sorted.
As the circuit is so big (and expensive to rent for over an hour), MSV decided to combine the SuperCup Grid with that of the TDC and Trackday Trophy. This meant we had a grid of over 50 cars, so it

SRS Automotive 2.0 TDI CR DSG 4Motion Caddy Race Van - Engine and Gearbox Build
Back in 2019 we collated all the build photos of Stef's SRS Automotive Caddy Van. You can view that by clicking the image below
The one thing is was missing was a proper engine! Stef suffered for a long time with only 240bhp, so we decided to give him the same Engine as our CitiGo which should give it a good kick up the rear!
Part 1 of the video is a walkaround of the van showing the attention to detail of the whole build, before we rip out the stock engine.
Part 2 shows us going th

750MC Birket Relay - Silverstone GP - 26th October 2019
Something a little different to what we normally do race wise, we decided early on in the year to enter the 750 Motor Club Birkett 6 Hour Relay Race which takes place every year at the end of October on the Silverstone GP Circuit.Instead of a straight race or normal endurance format, the relay element is for the driver AND car. Basically, a car and driver goes out, does their stint (which can be anything from 1 lap up to 3hrs of driving), and when they come back in the pits, a second car and d

New Diesel FWD World Record - Santa Pod - 28th & 29th May 2019
Last year with the Arosa was a disappointing one, mainly because we only managed to do just over 30 runs at Santa Pod over the full year, as we didn't get chance to do anything with it until BugJam in July. We also had the problem (as does everyone else) that with Santa Pod being the only purpose built drag strip currently in operation, whenever there is an event, the queues are so big that you can only grab a handful of runs each day. With the expense of preparing the car and getting to the str
