Mr Injector UK serviced four DI injectors from my A4 2.0 TFSI engine, previously with a persistent mis-fire, especially when cold and sometimes after a long journey. They were returned by next-day delivery, clean, with seals and accessories, ready to refit. The car is now perfectly smooth and slightly more economical. Communication by email was great throughout. The technical report was reassuring. A great result at a fraction of the price of new injectors. Thank you!
Really good service. James was Friendly, helpful and responded to any questions that I had via email. Would absolutely recommend using them.The injectors from my 1987 Jeep are BENDIX which are an unusual make, after a phone call and some pictures sent via email, James was able to confirm that they could be refurbished. Glad that I sent these to be checked TBH as it was discovered that they were leaking from the actual body's. I was advised that they were unfortunately not repairable and if used would cause an engine fire!!. Mr Injector has saved me from a potentially dangerous situation.. Thanks James 👍
