Disappointed with Green Line Auto

Be warned! If you own a Volvo and need repairs or a service, I would you not to take your vehicle to Green Line Auto. I took my vehicle, a Volvo XC90, T6 to Green Line Auto in November 2018 for a diagnosis as the engine light came on. They cleaned the Air Mass sensor and replaced the air filter - R2117. 3 Days later, the engine light came back on. The following week I took my vehicle back again to fix the error and to repair the leak of the water bottle for the windshield. Green Line Auto ordered an Airflow sensor from Midrand which was the wrong part. The engine light was then reset but the water bottle still leaked. On November 28, I instructed Shaun at Green Line Auto to order from Volvo's an Air Mass sensor. It would take about two weeks and they would have paid for it. On the 30th November, I visited Green Line Auto again to reset the engine light and I also paid them an amount of R4900 for the Air Mass sensor. I contacted the Volvo dealer (CMH) on the 11th of December to follow up on this order by Green Line Auto. They could not find such an order and explained to me the process prior to ordering any parts. They will first get a quote and if accepted by the client, a payment has to be made in advance before processing any orders. I confronted Shaun with this and he confirmed to me that they do not order parts from the parts division. I left it there. On the 15th of December my car started to misfire and I took the car back to Green Line Auto on the 13th December. They replaced a Coil pack at number 5 piston as well as the Air Mass Sensor they received from Volvo. I paid R450.00 for that. No job card was issued or an invoice given to me for payment. I was not informed at any time that their work and or the parts fitted, contain a guarantee. Needless to say the water bottle was still not repaired. Three days later, the engine light came back on again and I started to doubt whether they had in fact ordered the part from Volvo and whether they had replaced the right part. I asked Shaun to provide me with copies invoices of the Air Mass and Coil he ordered from Volvo. He stated that the invoices are in his father's bakkie and they are on holiday and would only be back on the 7th of January. At no stage did he confirm to me that there was a guarantee on their job and that I must bring my vehicle back to them to sort out the problem. To make a long story short, I decided to take my vehicle to a Volvo dealer. Their finding was that the inlet pipe to the air filter had a leak and had to be replace. It cost me R4742.60 but they also diagnosed a fault with the Air Mass Sensor. The fact is that the damaged inlet pipe was previously repaired by somebody else but it was visible to Green Line Auto who couldn't identify the problem and address the issue. Green Line Auto’s diagnosis was therefore not correct and the problem was right in front of their eyes to see. The end of the story was that I had to take the car back to Volvo to replace the Air Mass Sensor and it cost me R6700 to replace the part which was fitted by Green Line Auto. My advice to you is to get a second opinion or take your car to a repairer specializing in the type of vehicle you own. The fact that they are RMI does not mean that they will stand by their clients through thick and thin.
