I took my SL to Mastertech Assist for a B service. Initial communication was good although it became clear that the price quoted did not include all items that were due on my car such as brake fluid; I was told they check the car when you take it in for additional items, but since it was 2 years since the last B service new brake fluid was required so they re-quoted to include it and I decided to go ahead. It's nice to know up front what you'll be paying. When I got the car home I checked the oil level and was shocked to find it was way over the maximum level and up to the wire part of the dipstick. 1.6L of oil had to be extracted to get it to the correct level and I didn't drive the car during the interim period. When I checked the invoice I noticed that the oil used was not as per Mercedes spec for my 2009 petrol engine - a low ash oil was used which is only of benefit to diesel engine cars with a DPF. For older models the rule of thumb is to use the grade of oil Mercedes recommended when the car was in production and according to Mercedes' BeVo website the oil used was not the recommended spec. It's unclear whether the brake fluid was actually changed as the colour seemed a bit darker than new fluid would normally be. I have checked the before and after fluid and it appears to be identical in colour. Whilst the mileage was extremely low since the last change and the brake fluid potentially ok (no moisture) it was 2 years old so I wanted it changed as per Mercedes' recommendation. I was later assured it had been changed and was given the brand name (which incidentally does not appear to be one that meets Mercedes' MB331.0 spec). As someone else reported, I'm not sure if the car got the 50 point check over either as they didn't provide any kind of report to say it had been done. I understand from reading other reviews it is meant to go further than the Mercedes 37 point check but it would be nice to know what was checked. I requested details of what was checked but have not received any information. I was informed the washer fluid reservoir had a small leak but since getting the car home I have found no evidence of a leak over the last few weeks (the car is garaged so I would notice any leak). Mastertech replied to my first email and said the oil level was fine when they checked it but when I asked for their thoughts on how the level could have gone up so much after driving the car home and for further clarification on some of the other points above, they did not reply (I sent the second email 2 weeks ago). I'm very disappointed and would not recommend this company . I will be looking for a more reliable and honest garage going forward.

If you have a mercedes and don't want to pay through your nose, this garage is the place, £50/hour, courtesy car if required or they will pick up and drop off the car, I have had my car looked after by them for 4 years and they haven't given me any cause to criticize them, everything has been on point even thought I have to travel 35 miles to their garage in Droylsden, Manchester.
