We didn't even make it to the 8am official opening time before seeing a poor quality tuning file. This one's installed on a VW Golf MK7 GTD. Sadly cleaning up this sort of mess is becoming a daily occurrence.

2019 RangeRover Sport 3.0 TDV6 with a failed oil cooler that has contaminated the cooling system with engine oil.

New oil cooler fitted using all genuine LandRover parts. The cooling system was cleaned & flushed through throughly, we also replaced the coolant expansion tank as it was badly contaminated with oil.

We also replaced the engine front timing-belt & water-pump at the customer’s request. Luckily we got to it in time before it failed as you can see from the pictures that it’s been damaged when it was replaced by the last garage 😬
