Quick facts
- Part: Standard Ignition LDP27 evaporative emissions system leak detection pump
- Fits: 2007-2009 Volkswagen Touareg V8 4.2L and the 2007-2016 Touareg V6 3.6L
A check engine light with an evaporative emissions leak code can mean the pump has stopped working, but a cracked hose or a loose or damaged connector can set the same code. With the engine off and cool, look over the hose connections and wiring connector for cracks or looseness before replacing the pump; a shop can run the vacuum and electrical tests.

Frequently Asked Questions
Is the Standard Ignition LDP27 leak detection pump right for the 2007-2016 Volkswagen Touareg V6 3.6L?
Yes. Standard Ignition LDP27 fits the 2007-2016 Volkswagen Touareg V6 3.6L and the 2007-2009 Touareg V8 4.2L.
What kind of electrical connector does the LDP27 have?
Standard Ignition LDP27 has one female connector with three male blade terminals. It also has two hose connectors.
What do the diaphragm and spring in this leak detection pump do?
Together they open and close to send the switch accurate voltage readings, and both are precision-calibrated. Standard Ignition LDP27 relies on engine vacuum to detect evaporative leaks.
Can a failing leak detection pump turn on the check engine light?
It can. A pump that no longer detects leaks properly can set an evaporative emissions fault code and light the check engine light, and a shop can confirm it with a scan.
Does the Standard Ignition LDP27 replace part number 7L0906271B?
Yes. 7L0906271B is on the interchange list for Standard Ignition LDP27, along with 7L0906271C, VDP27, ESM1024 and 2-71026.
