E90 330i in recently for some track day preparation, as its first outing is Donington Park in November. Not only did I upgrade the brakes, but I also fixed an oil leak from the filter housing and replaced all the worn front suspension arms and drop links. Also a fresh set of Kumho PS72 rubber all round.

Possibly some coilovers and bushes being upgraded at later date .

Good Afternoon!

The workshop will be closed for a few days over the next couple of weeks.

Firstly, Monday 26th October as I shall be whizzing around Castle Combe Circuit on a track day.
Sorry but I won't be taking any calls or messages that day.

Secondly, Monday 2nd & Tuesday 3rd November, due to extensive site maintenance being carried out, and I won't be able to access the workshop.

I will however be taking calls and messages during the 2 days within working hours as normal.
It will just be from home lol.

Thank you kindly for your understanding

Good morning, hope you're all well.

Polite note regarding MOTs.

If you wish to book an MOT with me, please give me at least 3 to 4 weeks notice.

I am incredibly busy in the workshop at the moment and don't have the time to go off and get one done last minute.

If booked with enough notice, I can then organise my other work around the MOT appointment.

Many thanks

Good Afternoon

I am sorry, but with immediate effect, I am having to increase some prices.

This will be mostly on servicing, as engine oil and other oils/fluids etc have increased dramatically in price since the goings on in the Middle East.

Also I am noticing some parts are increasing in price due to rising manufacturing costs and fuel prices.

I have been able to keep costs reasonable to customers until now while using up old stock. But now I am moving on to the new prices of oil etc , and simply I just cannot cover the costs.

Some oils have risen buy around £300 a barrel and could get higher.

Once again my apologies, and I thank you for your understanding 🫶

Best Wishes
Justin

2016 Mercedes C200 in with Adblue issues.

400 miles until no start and fault codes relating to an Adblue system fault.

These systems can be very costly to repair, and so the customer opted for me to carry out an Adblue solution.

This is a permanent resolve, and the vehicle can be used as normal without the worry of shutting down.

A 2017 Focus RS was in last week. Unfortunately, the owner caught a small pole sticking out of the ground, and it went through the lower bumper grill, causing damage to both the intercooler and the AC condenser, losing all the gas. And very luckily, it didn't take out the radiator with it.

I sourced a new genuine condenser from Ford and the customer got hold of a good second hand intercooler and bumper grill.

Got it all back together, checked for leaks and regassed the AC. 😉💪

Definitely seeing a few A/C leaks lately. This time, a damaged condenser on a Nissan Juke.

Without the bumper, it looks like a Transformer halfway through its transition, lol.

2018 Vauxhall Grandland X

These PSA-based vehicles commonly have AdBlue issues, which can be quite costly to repair.

The customer chose the more cost-effective route and opted for an AdBlue solution, thus permanently removing any further AdBlue issues.

The customer can now go about their business, and use the vehicle as normal 😉

Mk2 Ford KA in having a replacement A/C Condenser.

The old one had definitely seen better days .

Now repaired and refilled with new refrigerant, it's keeping the owner nice and cool 👍

2003 Vauxhall Astra G in for some TLC.

A/C condenser had a leak, and customer wanted it replaced ahead of the next heatwave🔥

Now the system is leak free and topped up with new Refrigerant (r134a) , the temp coming through the air vents is a cool 8°.

Not bad for a car 23 years old 💪
