Product Description
We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes sooner
This valve is an upgrade for the 2.0 turbocharged M133 DE20 LA (265 kW 355BHP version) engine found in the Mercedes AMG A45 up to 2015. The engine as supplied by AMG has a port for a dump valve on the side of the turbo, but it is blanked off. Whilst this is fine for the stock level of tune, as the boost is turned up when the car is remapped, driveability can be effected and the car can stutter on hard acceleration, which ultimately will reduce the life of the turbo.



Our valve bolts straight up to the turbo and is supplied with appropriate hardware in order to source vacuum to operate the valve. The valve features an aluminium piston for longevity, and is fully serviceable and can be rebuilt with a range of springs to suit your level of power.
If you are unsure if your model is compatible please check to see if your model has the diverter valve blank off plate (compatible models), or solenoid type diverter valve (incompatible models).

⭐ "Fitted to my Facelift A45 AMG. Takes some time to fit but once installed in my opinion is well worth it. Sounds great, loud enough to put a smile on your face but not intrusive. Also a great add on for anyone going Stage 2. Thanks again ⭐"

Warranty
10 Year Warranty Information
The majority of Forge Motorsport products come with a limited 10 Year Warranty (brakes pads excluded). All warranty claims must be accompanied by the original proof of purchase to enable us to help you. Failure to supply this proof will result in your claim or enquiry being denied.
For further information, please call our customer service team on +49(0)3222/1097-308 or email info@forgemotorsport.eu.
Do not use aggressive (acidic) car cleaning products, particularly traffic film remover solutions or shampoos to clean your intercooler, radiator, or oil cooler. The use of these products can damage Forge Motorsport cooling systems and invalidate your warranty. These are often found at car washes. A light, warm, soapy solution (free of harsh acidic cleaning compounds) should be used to clean you cooler and thoroughly rinsed away. We recommend that you should inspect your product on a regular basis for bent and/or crushed fins. Any bent fins should be carefully straightened to allow ambient air to pass through the core face. At the time of installing your Forge radiator, an approved coolant must be used and added to the coolant system. Be sure you never mix coolant and always use distilled water.
This warranty does not apply to any defect in the goods arising from fair wear and tear, wilful damage, accident, negligence by you or any third party, use otherwise than as recommended by the supplier, failure to follow the supplier’s instructions, or any alteration or repair carried out without the supplier’s approval.

Will this fit on a gla 45 amg x156.
if the vehicle is a pre face lift and has the divertor valve blank on the turbo yes the forge valve will fit. if it has the later electronic valve it will not be compatible.
