Bosch17025 Oxygen Sensor

Extremely pleased with this purchase for my 2002 VW Passat 1.8T. It is almost one fifth of the price from my local garage - but is exactly the same product! I was a bit dubious at first, but I searched on the Bosch website for my vehicle model number - and up came this part number. So I was confident that it was the correct part, but thought maybe it was manufactured elsewhere, so perhaps not so good quality?But I was wrong! This is a 100% genuine full-spec Bosch part manufactured in Germany. See the pictures of the packaging I have uploaded. The sensor comes complete with a full installation kit and has the proper connector already fitted. Some other sensors don't include this and you have to fit the connector yourself.It is now installed in my car, and it works perfectly. I wasn't sure if my sensor needed replacing but after replacing half a dozen other components in the vacuum system and still having the MIL light coming on, I thought it worth a try, especially at this amazing price.A couple of tips if you are thinking of buying one. Firstly, do NOT remove the protective cap from the sensor until you intend to install it. It is there to keep the special lubricant in place so you can remove it in the future. Secondly, you must remove the old sensor whilst the exhaust is hot otherwise you can't get it out. Be very careful, protect your arms and hands from burns from the exhaust and engine block. Thirdly you must use a special 22mm oxygen sensor socket spanner, they are about £10 - but its impossible to remove without one.It appears to be a recommendation to replace this (upstream) sensor every 100K miles. My car has only done about 65K but the sensor had been contaminated with a silicon sealer used to seal the rocker gasket. Oxygen sensors do NOT like silicon - mine worked but was slow response, reduced the engine power output and caused lumpy idling. Much better now.

good

Perfect example why you should choose the proper OEM part. tried a cheaper make and it caused all sorts of problems. replaced with this one and perfect driving is back again.

OK

All parts good

Original OEM MAF. Works as expected.

Failed after less than 500 miles, sadly 2 months after purchase and Amazon won't touch after a month. Last one lasted 8 years. Pretty poor all round, states a 2 year warranty but your left high an dry by Amazon, as usual!

SENSOR MAF PERFECTO PARA MI MERCEDES BENZ C240 AÑO 2002 2.6 LITROS, 6 CILINDROS. PERFECTO.

Bosch 02 sensors are top quality. The install is plug and play just make sure when installing make sure you have the correct bank and up stream ( before the cat down stream after the cat) not complaints

Product was great. It worked perfect.

Worked fine. Well packed. Good quality. Great connector!

I have a 2012 BMW X5 50I M package, fit perfect.I’m so happy. 👍🏼
